Talking DIY Retro-styled voltage/value meter?

Ohnoes, again TiN posting teh "guess me" threads?
Lucky you, not today

In ancient times, when dinosaurs was overclocking first 2-bit computers, there was
vaccum lamps filled with gas, which can show nicely glow letters and symbols.
These lamps were widely used in past century, in variuos calculators, freq meters,
counters and such..

I will use SSSR lamps manufactured in 1974-1978 years . They are available for sale even today.

I had these lamps for a while, until one day decided to make lamp readout panel.
For start decided to make it as a clock, to cover development expenses, by selling few.
So this is the start of this project. Welcome.

It's using ancient lamps but except them everything else is very latest technology, 32bit MCU,
programmable logic and SMT tech involved.

We have main blocks here:

32bit ARM7 CPU with internal 128KB of Flash and 32KB of RAM.
10bit analog-to-digital convertor for temperature/voltage/current etc measurement.
Battery-powered real-time clock chip DS1340
Date and time counting
4 buttons for user input and control
Temperature sensor
ALTERA 240-element MAX II programmable logic chip with 12-channel 8bit PWM, and SPI slave logic.
Voltage sensor with protection for mains measurement
Protection for every critical part
20pin JTAG programmin port (for development)

Lamp section:

6 lamps IN-12Б via sockets or soldered thru board.
6/4 RGB leds under each lamp, totally controllable
Transistors for voltage switching near lamps (each lamp need +170 V to operate)

Power supply

External 220В > 12V PSU, like one from mobile phone etc.
LDO to get 12V > 3.3V for CPU power
Boost step-up convertor 12V > ~150V to power lamps.

At this moment, i'm in pcb and enclosure design. Need suggestions about better enclosure
I think it must be wooden, like retro, old-school stuff.

Top view on PCB with parts.



Bottom view on PCB with parts



Perspective 3d view with wireframes



Cutted pcb, that white square box under lamp is 3-color RGB led.



First enclosure variant? How it is looking?



Internal compartment.



This project is totally OPEN. Opensource and openhardware.

web-based project management TRAC : http://home.xdevs.com:8000/nixie
repository with files (Mercurial) : http://home.xdevs.com:8001

Welcome to discuss this project. I need your opinions. *beer*

At this time i managed to get prototype on breadboard showing time at similar IN-16 lamps:



IN-12 lamps glow like this:







I promise to cover project progress here, on kingpincooling.com forums, exclusively in english, hope admins dont ban me for lotz of picz

These lights are so sick. They are even sicker live. They remind me of something post apocalyptic.

Check out this rectumfrier : http://www.youtube.com/watch?v=KGb-n...1&feature=fvwp


I love old tubes. 300B SET mesh plate is where the action is at for audio...

so all of you think that i should post more about this ugly project here?

I have a problem with enclosure for this, coz no CNC available here to cut nice parts from pile of wood.
Ugly rect box looks badly And i have noidea what to do better

Raja, OMG, that's some evil stuff there.

rendered another prespective view of pcb assy

Yeah those mercury filled rectifiers are scary. A few years ago I had something planned with the 866A half wave (man those look awesome when lit up, they are from the 1940s so kinda risky to use) http://www.google.co.uk/images?hl=en...w=1920&bih=953

I settled on the AZ1 mesh plate instead. Some of the old gas filled tube regulators look nice too (although the voltage is way higher than what you need for this.)

I'm too young for that freakin stuff, Raja
most hardcore thing i had is generator lamp GU81M



Wanted to make VTTC with Tesla transformer for fun, but hadn't enuf motivation

I prefer semiconductors

And back ontopic:
Found my pile of nixies



Too much voltage:



And have some issues with breadboard for testing. Power mosfet of step-up boost convertor badly smoked at night, so i had to wake up and shut down it.
need to rework that.
